To all whom "it may concern:

Be it known that I, LIARL Unmcn, a sat iect of the German Emperor. and resident of .do. 21 l abrikstrasse, Zweibriieken, Pfalz, Germany, have invented certain new and useful Improvements in Devices for Damping the Air in Closed Rooms, of which the following is a specification.

In spinning and weaving-mills and other textile factories in general, and in particular in silk-spinning and silk-w aving millsg also in tobacco-factories, the work is made ditlicult during the dry time of the year by the fact that in consequence of the dry air the fibrous material and the tobaccodeaves become very easily brittle and are apt to crumble, whereby there is not only formed dust, which the workers have to inhale, but a great deal of material also is lost, as well as time, as in silk-spinning and silk-weaving mills and in textile factories in gene-a1 the broken threads require to be tied together again. By this work an extraordinary great deal of time is lost, so tliat on such days the output is often reduced to about two thirds. But also in hospitals, especially in those for pulmonic patients, where a damp atmosphere is a necessary condition for a favorable course of the disease the dryness of the air is very unpleasantly felt. it has frequently been attempted to remove this drawba sk by finely spraying water and mixing it with the air, to form av kind of fog, or by letting steam pass out through holes in a steameonduit. Both processes have their drawbacks. The water-fog is deposited in spinning and weaving-mills on the metal parts, so that they become rusty, which is in silkspinning and silk-weaving mills particularly dangerous. The same applies to the simple distribution of steam, especially as at the opening through which the steam passes outthere takes place a coiuleusation and the formation of drops which, when they fall down, fall partly on the machinery and partly on the silk and damage the same. Moreover by the formation of fog or the ordinary distribution of steam, it is not possible to moisten the air in the whole room uniformly it special distributing-ventilators are not used. These cause d 'afts which are likewise to be avoided in silk-spinning and weaving-mills as well as in hospitals.

The object of the present invention is to effect in all the above-mentioned cases uniform moistening of the airy and in such a manner that no injurious deposits or prod nets of condensation are formed and no further movement of the air is necessary. According to the same steam is likewise introduced into the respective workr00m or hospital-room, but the steam, before it passes into the room, is freed of the water contained in it by; a special spray-nozzle and the product. of the condensation formed in the latter is caused to pass into a proportion ately narrow conduit, running along the steam-comluit, below or above the same, so that the air cannot be polluted by the product of the condensation. in order to prevent a detrimental cooling of the steam-conduit and of the spray-nozzles as well as a nonintended giving-elf of heat through the same, they are covered in the well known manner by a mass which prevents this. But in order to avoid the formation of a vacuum in the conduit and thereby a passing over of the steaiii from the spray-nozzle into the latter, the conduitconveying the product of condensation is covered with a similar mass, so that the steam entering the said conduit can exert a certain counter-pressure upon the steam in the spray-nozzles.

The drawing, wherein similar letters refe to similar parts throughout the several views, illustrates in Figure l a part of the steamconduit a and of the conduit Z) for the condensed steam with the spray nozzlcs c in a front view and in Fig. 2' in a eross-section. Theconduit for the condensed steam is in this case arranged below the steam-conduit. In Figs. 3 and l are shown two other forms of the arrangement of the conduits for the steam and condensed steamin a cross-section and in Fig. 3 the conduit for the condensed steam is arranged by the side of the steamconduit, while in the ar -angement according to Fig. 4: it surrounds the steam-conduit c0ncentrically. Fig. 5 shows a spray-nozzle in a longitudinal section, while Figs. 6, 7 and 8 show a cross-section of the same on the lines AB, CD and E-F.

1t is advantageous to connect the two conduits a and b so with each other that they form a rigid whole, as otherwise the connections with the spray-nozzle would too easily be made untight by the mutual movements, .and drops would be formed as a result. In

the form of construction according to l i l to 3 both conduits, aand hare in the first place supported by props a, and after they have been covered with the coating-mass e hey are united with each other by bows placed over the latter. In the form of construction according to Fig. t the conduit 6 for the condensed steam surrounding the steam-conduit is only so large that there remains between the two a narrow concentric interspace g for receiving the steam to be condensed. The conduit a can be supported in the conduit 7) by ribs or, as shown in Fig. l

4:, by supporting bolts or screws h, inserted into the conduit b. This arrangement, itis true, makes it necessary to make the conduit a little larger, but the conduit a is thereby protected the better against losses of heat, as it is in the first place surrounded by the condensation-room and further by the mass e for preventing the loss of heat.

The spray-nozzle c, which stands in coinmunication by a tube 2' which can be shut off, with the steam-conduit, and by a thin and partly spiral tube with the condensationconduit, is preferably made of a casing formed by two double cones, into one of whose ends opens the connecting-conduit i, while at, the other end there passes out the earn sprayingtube Z. The inside of the casing of the nozzle is divided by partitionwalls at, m and a capsule-shaped partitionwall 172, into four spaces a, a a and/n The tube 2' projects into the room a and is open in front as well as provided at the top with an outlet opening '0. The partition Wall m in front of the mouth of this tube 2' is fitted out, near the border, with steamoutlets r. The tube Z, which lets the steam pass out of the spray-nozzle, projects rather far into the room a of the nozzle, and is surrounded by the capsule-shaped partition wall m which is provided on its circumference with steam outlets a. From the lower part of the cap there branches oil a condensing-tube a opening into the space a of the nozzle. The partition wall m itself is provided at the bottom with an opening m for letting through the waste-water. It the nozzles are arranged under an angle of about 45, the tube is for'lctting old the waste-water is inserted into the casing of the nozzle close to the partition-Wall But if the spraynozzles are arranged vertically, the tube 70 must open into the casing of the nozzle close to y. the inside of the nozzle is the following: Coming out of the tube 2' it passes into the room a, rebounds on the one side on the partition-wall m and, on the other, if it passes out through the opening 0, it rebounds on the upper wall of the casing of the nozzle, is distributed in the room, enters through the openings 7* of the partition wall into the room a of the nozzle and from here through the openings s into the space a of the nozzle and then into the spray tube Z, through which it leaves the nozzle. The particles of water separated in the different rooms collect The course which the steam takes in at the lowest place of the nozzle and enter into the tube is through which they are conducted into the tube for letting oil the wastewater. In consequence of the fact that the spray-tube freely projects into the last room .of the nozzle water carried along the wall of the nozzle by the rush of the steam cannot get to the outlet-tube, so that it can be fully relied on that only steam freed of water can pass out.
